Abstract:

A series of five experimental projects and three demonstration projects were constructed to better understand the performance of pavement overlays using various levels of asphalt binder replacement (ABR) from reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and crushed concrete. The ABR varied from 15% to 60% in the experimental sections. The study of these projects prior to construction, during construction, and for a short monitoring period after construction is intended to determine the impact of various pre-existing pavement conditions, pavement cross-section, mix design, and material properties on the ultimate performance of the asphalt concrete (AC) overlay. This final report is the third report on this research project. Two interim reports that documented project construction and performance to date have been previously published. This report documents final material testing, performance data collection of distress and profile surveys after construction. This report provides a compilation of findings and recommendations from all stages of these projects. The testing suite included Cantabro, stability/flow, Texas overlay, Illinois Flexibility Index Test (I-FIT), fatigue, modulus, creep, and Hamburg rutting. Pavement performance as measured by transverse cracking was found to be more pronounced in thin AC overlays than in thick AC overlays. The Flexibility Index was found to correlate to transverse cracking and confirmed the validity of using this parameter in mix design development.
